Theoretical calculations predict a complex excited state (0+) for helium-4 (4He) at the 20.21 MeV energy level. This state involves a coupling of three cluster configurations: hydrogen-3 and a proton, ...

An important part of physics research is examining why theoretical calculations and experimental results sometimes don't match. A recent experiment in Germany studied the helium-4 nucleus, also known ...

Scientists at CERN have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact. This is an ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

This is an example track of an alpha particle (energy 15 MeV) from the test beam registered with the demonstrator detector mini-eTPC. Read-out electrodes of the detector are parallel to the X-Y plane, ...
